I have this same issue when I compile to PDF from the standard templates. If I change to my own template, it fixes the name (only after exporting the PList, editing it, saving it and importing it) but the story title is still ePubTest.
The meta data item doesn’t appear on the left with any custom format, so Im a little at a loss regarding what I was supposed to do that I missed.
Where is the information appearing? Check the “Meta-Data” pane of compile if it is appearing in an epub or suchlike, the headers and footers in “Page Settings” if it’s in a header or footer, or the title page in your project itself.
Also, make sure you are using the latest version of Scrivener (2.1). An early version of Scrivener 2.0 shipped with templates that accidentally had my name in, although this was rectified within a week. Maybe you are using a project that was created with that version?
